probe sideways during a phase of the probing action in 
which a probe tip (38) is moved against the surface to be 
tested, blockage of an air outlet occurring if the 
surface is unthreaded. The resulting increase in air 
pressure is detected by a pressure switch to enable 
operation of a fault signal. The probe tip (38) is slidably 
mounted in the main body of the probe to be moved back 
as the probe is advanced towards the workpiece in the 
initial phase of the test if a bore is absent or a 
broken tool is lodged therein, with porting shutting off 
air flow to the tip air outlet to also cause an increase 
in back pressure enabling generation of a fault signal.

Abstract: A bolted repair for curved surfaces of an 
aircraft structure (10) includes a plurality of 
relatively thin, flexible plates (14, 16, 18, 20) that are bent to 
conform to the surface, either individually or as 
a group. After the plates have been bent to conform 
to the surface, layers of adhesive (15) are applied 
between adjacent plates to bond the plates to each 
other. The resulting stack of bonded plates is then 
secured to the structure with fasteners extending 
through attachment holes in the stack and 
structure. The plates may be bent by first securing 
a portion of a stack of plates to the structure and 
then bending the stack of plates so that the plates 
progressively conform to the surface of the 
structure. As areas of the stack of plates conform 
to the surface of said structure, the areas are 
temporarily secured to the structure with temporary 
fasteners (34, 38, 42, 44) until the entire surface of the stack of 
plates has been bent to conform to the surface of 
the structure. After layers of adhesive are applied 
between adjacent plates and all of the temporary 
fasteners have been installed so that the entire 
surface of the stack of plates conforms to the 
surface of the structure, the temporary fasteners (34, 38, 42, 44) 
are sequentially removed and permanent fasteners 
are installed in their places.

Patent EP-0360229-A3 (EP)
IPC: F25J1/02
Filed: 1989-09-19
Abstract: The present invention is an improvement to a liquefaction process 
for natural gas, wherein refrigeration for the liquefaction process is 
provided by two closed-loop refrigeration cycles. The first or low level 
refrigeration cycle uses either a mixed refrigerant or a single component 
refrigerant as the heat pump fluid, and the second or high level 
refrigeration  cycle uses a mixed (multicomponent) 
refrigerant as the heat pump 
fluid. In the liquefaction process the second or high level 
refrigeration cycle cools the low level heat pump fluid. The low level 
refrigeration cycle cools and liquefies the cooled natural gas feed. The 
improvement to the process is the use of an absorption refrigeration 
cycle to precool the natural gas feed, the low level heat pump fluid, the 
high level heat pump fluid and, if required, the deep flash recycle. 
Heat to drive the absorption refrigeration cycle is provided by the 
exhaust gas from one or more drives for the compressors in the process.

IPC: H01L21/208
Filed: 1989-08-02
Abstract: An electro-optical device with a transparent 
substrate (210) is produced by epitaxially first growing the 
device layers (220), followed by that of the transparent 
substrate layer (210) on an opaque wafer (200). The opaque wafer (200) is 
subsequently removed. The device layers (220) have dopants 
with sufficient low diffusivities that their electronic 
characteristics are not adversely affected by long 
exposure to elevated temperature during the growth of the 
transparent substrate layer. In a liquid phase epitaxy 
(LPE) method, a repeated temperature cycle technique is 
used where the temperature is repeatedly raised up each 
time after cooling to provide a large cooling range for 
growing a sufficiently thick substrate layer (210) or a series 
of device layers (220). In between growths and during the 
temperature heat-up periods, the device is stored within 
the LPE reactor. In other embodiments, the device is 
either temporarily removed from the LPE reactor or is 
transferred to another reactor. When a epitaxial layer 
is oxidizable, a non-oxidizable cap is temporarily grown 
on it in between growths and during the temperature heat-­
up periods. The cap is subsequently removed by melting 
back at an elevated temperature just prior to the growth 
of a next layer.
